The retionale for this protocol was the timing of first CNS relapses in patients not receiving prophylaxis which suggests that leukemic colonization of the CNS is not restricted to the initial stage of the disease and that periodic measures might be advantageous. The low dosage of radiation was chosen because it is well tolerated and has been found temporarily effective in overt CNS relapse. The two series of patients were comparable as to various parameters. Results after three years of observation were comparable to those obtained by others with a single initial course of high\u2010dose radiation, with an expected 50% uninterrupted complete 5\u2010year remission. On the basis of 30 months follow up in 26 patients, the therapy is well tolerated. An increase in morbidity due to infections in remission was not associated with a higher mortality.<\/jats:p>","DOI":"10.1002\/ajh.2830010203","type":"journal-article","created":{"date-parts":[[2007,2,21]],"date-time":"2007-02-21T04:47:11Z","timestamp":1172033231000},"page":"191-199","source":"Crossref","is-referenced-by-count":19,"title":["IMFRA (Intermittent Intrathecal Methotrexate and Fractional Radiation) plus chemotherapy in childhood leukemia"],"prefix":"10.1002","volume":"1","author":[{"given":"W.
